Inverted pyramid-texturing of silicon surface has been proven to have great application potential in solar cells. In this paper, we utilized Ag-assisted chemical etching (Ag–ACE) technology combing with polyvinylpyrrolidone (PVP) fabricate an inverted pyramid textured Si surface. We call it Ag@PVP–ACE. The effect different experimental parameters on results was observed. show that the microstru...

This paper presents a framework for modeling, animating and morphing textured implicit models. Our hierarchical skeletal implicit surface model incorporates key-frame animation and procedural solid texturing in a unified and coherent way. Our system enables the designer to create complex special effects by synchronizing shape, animation and texture transformations.

Surface texturing is used to increase hydrodynamic pressure and reduce friction and wear between parallel sliding surfaces in a variety of applications. The shape, geometry, and density of the patterned microtexture features play a key role in the tribological performance of such textured slider bearings. Lubrication models are used to predict the load-carrying capacity, friction coefficient, a...

Silicon, as the most abundant element in earth’s crust and common material used electronic optical equipment, has attracted attention of many individuals to change properties this material, improving its properties. One these efforts relies on reduction surface reflection by making use different methods. However, among them, lasers creating microstructures been special importance because there ...

The use of lubricants (solid or liquid) is a well-known and suitable approach to reduce friction and wear of moving machine components. Another possibility to influence the tribological behaviour is the formation of well-defined surface topographies such as dimples, bumps or lattice-like pattern geometries by laser surface texturing. However, both methods are limited in their effect: surface te...

The creation of 3D models is a fundamental task in computer graphics. The task is required by professional artists working on movies, television, and games, and desired by casual users who wish to make their own models for use in virtual worlds or as a hobby. In this thesis, we consider approaches to creating and editing 3D models that minimize the user’s thinking in 3D. In particular, our appr...
